Clarrification of returnCodes variable

[vsmalladi]

Currently there is a discrepancy in naming convention of returnCodes and the example as return_code or return_codes

According to the WDL Spec

Need clarification on naming convention for compliance suite, issue in miniwdl #729

From @peterhuene
" If i'm understanding correctly, we should fix the returnCodes examples in 1.1.3 to use the lower camel case; all of the requirements in 1.2 already use the snake case form in their specifications and use the lower camel case as "aliases", we should probably scrub the examples of any lower camel case uses of the requirements/hints in a patch to 1.2 (if there are any) and deprecate the aliases in 1.3 to be removed in 2.0, perhaps?"
